Re: IOS crashed 2600 Series

Hello Vikas,

You would have to download the IOS again from a good source (preferably Cisco) and try again. You can also verify the checksum with the following command :

Router#verify /md5 'Put the correct checksum here' flash: c2600-i-mz.123-22a.bin

Hope this helps,

Ratish
